SPECIFICATION forming partof Letters Patent No. 278,729, dated June 5,1883.

Application filed November 524, 1882. (No model.)

To aZZ whom it may concern: 7

Be it known that I, DEXTER W. PARKER, a citizen of the United States,residing at Meriden, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inLamp-Supports and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying draw ings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to the auxiliary pieces which are usuallyattached to lamp-brackets.

- Hitherto such pieces have been made of cast metal, their ornamentalconfiguration and marking being given by the molds in which they arecast. The pieces thus manufactured are necessarily heavy, and musteither be practically in one piece with the bracket, or will be indanger of accidentally falling off and injuring persons or things below.This last defeet is specially noticeable in the case of extension-lamps,which are ordinarily arranged directly over a table and suspended partlyor wholly by chains- If the suspending devices break, the fall of thelamp is made more formidable by the cast metal ornaments attached to orformed with its harp or other parts of the fixture. Moreover, in theprocess of casting it is impossible to produce cheaply the desiredfineness of ornamental lines and surfaces, and the figures of suchsurfaces are often indistinct.

The object of my present invention is to cure these defects, and this Iaccomplish by substituting for the ordinary heavy castmet-al piecesabove referred to light sheet-metal auxiliary pieces, which may beeasily detached from the lamp, and which are shaped and ornamented bystriking up, thus receiving fine, accurate, and distinct lines andfigures.

It is obvious that such auxiliary pieces, as compared with the old ones,will materially lessen the bulk required in the counterbalancing-weight,and thus effect a double diminution of the weight of the fixture as awhole, besides diminishing also the size of the weight and the dangerthat it will do damage by falling if detached.

3 represents an extension-lamp having itsharp provided with similarauxiliary pieces in the same'manner. Fig. 4 is a detail view of part ofa lamp-supporting bracket and an auxiliary piece. Fig. 5 represents avertical section through line :0 w of Fig. 2.

In said drawings, A designates the lamp, B the shade thereof, 0 thesupport,.andD Dthe auxiliary pieces.

The support 0 may be of any form convenient to the special use intended.Thus in Fig. 1 it is a bar swiveled to turn laterally, and resembling anordinary form of gas-fixture for walls, while in Fig. 3 it is the well-known harp of an extension-lamp.

Each of the ornamental auxiliary pieces I) D consists of two counterpartshells having their concave sides toward one another and se cured firmlyat the edges. They are provided with lugs or studs (1, which set intorecesses of the bracket or support and are secured thereto.

It is not necessary that the pieces D D should be made each in twoparts, for an ornamental piece stamped out of one part will answer verywell in many instances. In stamping or striking up these auxiliarypieces I form a variety of lines and figures in relief. As these linesand figures are not superficial, but involve the bending of the entirethickness of metal in said pieces, the latter are necessarily stiffenedby the process, and a less thickness of metal will answer the purposethan would otherwise be required. An additional advantage is derivedfrom striking up as a preparation for electroplating.

Cast-metal ornamentsrequire to be smoothed by polishing wheels I beforeelectroplating is practicable; but my process makes thisstepunnecessary, since the same operation that produces the ornamentsalso smooths them. These auxiliary pieces may be used on gas fixtures orchandeliers.

WVhen desired, they may be made in one piece withthe lamp-support, andafterward ornamented, as set forth.

v Having thus fully described my invention, what Iclaim as new, anddesire to secure by Letters Patent of the United States, is-

1. In combinationwithalamp or gas bracket port, a sheet-metal auxiliarypiece struck up or support, as sheet-metal auxiliary piece, for to formstiffening lines and figures in relief. 10
